HIGH-RELIABILITY LOW-DEFECT SEMICONDUCTOR LIGHT-EMITTING DEVICE AND METHOD FOR MANUFACTURING SAME

A high-reliability low-defect semiconductor light-emitting device and a method for manufacturing same. The high-reliability low-defect semiconductor light-emitting device includes: a semiconductor substrate layer; an active layer arranged on the semiconductor substrate layer; a doped semiconductor contact layer arranged on a side of the active layer away from the semiconductor substrate layer, where the doped semiconductor contact layer includes a first area and an edge area surrounding the first area; a protection layer arranged on a side of the edge area of the doped semiconductor contact layer away from the active layer; and a front electrode layer, arranged on a side of the first area away from the active layer, where an upper surface of the front electrode layer in the first area is lower than an upper surface of the protection layer. The semiconductor light-emitting device has both high reliability and reduced process control costs.
